java抓包代码,java抓包什么意思

如何通过抓包工具fiddler获取java程序的http请求的代码详情

java程序需要设置proxy才能生效：

String url="";  

Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress("127.0.0.1", 8888));  

URL serverUrl = new URL(url);  

HttpURLConnection conn = (HttpURLConnection) serverUrl.openConnection(proxy);

Q2: 用Eclipse Java 写了一个程序在不显示代码的情况下如何将程序展示给别人看，用cmd抓包的具体如何操作？

1.确保写的类没问题，java程序是先编译，后执行

2.打开cmd，进入该文件所在路径，输入javac -d 类名.java，对该java源文件编译，生成class文件

3.再输入java 类名 ,就可以运行这个程序了。

如果有多个类，需要写个bat批处理文件，即同时运行多个java类、jar包、配置文件、资源文件。
